The iShares MSCI USA Momentum Factor ETF (MTUM) is designed to track the performance of U.S. large- and mid-cap stocks exhibiting relatively higher price momentum. Launched in 2013, MTUM provides targeted exposure to stocks with strong recent price appreciation, adjusted for volatility. The fund employs a systematic approach to momentum investing, traditionally associated with the tendency of winning stocks to continue outperforming and losing stocks to continue underperforming. The strategy incorporates risk adjustment in its momentum calculation, favoring stocks with high risk-adjusted returns rather than simply high absolute returns.
